電(dian)池行業制備超水(shui)的工藝：

1、采(cai)用離子(zi)交換方(fang)式(shi)，其流(liu)程(cheng)如下： 

原水(shui)→原水(shui)加(jia)壓泵→多介質過(guo)(guo)濾(lv)(lv)器(qi)→活(huo)性炭(tan)過(guo)(guo)濾(lv)(lv)器(qi)→軟水(shui)器(qi)→精密過(guo)(guo)濾(lv)(lv)器(qi)→陽樹(shu)脂過(guo)(guo)濾(lv)(lv)床(chuang)→陰(yin)樹(shu)脂過(guo)(guo)濾(lv)(lv)床(chuang)→陰(yin)陽樹(shu)脂混床(chuang)→微(wei)孔過(guo)(guo)濾(lv)(lv)器(qi)→用水(shui)點(dian)

2、采用兩級反滲透方式，其流程(cheng)如下： 

原水→原水加壓泵(beng)→多介(jie)質過濾器(qi)→活性(xing)炭過濾器(qi)→軟水器(qi)→精(jing)密(mi)過濾器(qi)→一(yi)級反(fan)滲(shen)透 →PH調節→中間水箱→二級反(fan)滲(shen)透（反(fan)滲(shen)透膜(mo)表面帶正(zheng)電(dian)荷(he)）→純化水箱→純水泵(beng)→微孔過濾器(qi)→用(yong)水點

3、采用EDI方式，其流程如下： 

原水(shui)→原水(shui)加(jia)壓泵→多介質過(guo)濾器(qi)→活性炭過(guo)濾器(qi)→軟水(shui)器(qi)→精(jing)密過(guo)濾器(qi)→一級反滲透機→中間水(shui)箱(xiang)→中間水(shui)泵→EDI系統(tong)→微孔過(guo)濾器(qi)→用水(shui)點(dian) 

工藝簡介：

    反滲透技術是一(yi)種高(gao)效(xiao)率、低能(neng)耗能(neng)、無污染的(de)先進技術，主(zhu)要(yao)應用于純水制備與海水淡化。反滲透技術是利用壓力(li)差為動力(li)的(de)膜分離(li)過濾(lv)技術，通過壓力(li)差將H2O與源水中的(de)無機鹽、重(zhong)金屬離(li)子(zi)、有機物、膠(jiao)體、細菌(jun)、病毒(du)等雜質(zhi)嚴格(ge)分離(li)。

    EDI是一種電滲(shen)析技(ji)術(shu)和離(li)子交(jiao)換(huan)(huan)技(ji)術(shu)相融合(he)的(de)先進技(ji)術(shu)，系(xi)統能(neng)夠(gou)通過電磁(ci)場(chang)通過陰、陽(yang)(yang)離(li)子交(jiao)換(huan)(huan)膜對陰、陽(yang)(yang)離(li)子的(de)選擇性(xing)透過作(zuo)用(yong)(yong)與離(li)子交(jiao)換(huan)(huan)樹脂對離(li)子的(de)交(jiao)換(huan)(huan)作(zuo)用(yong)(yong)，在(zai)直流電場(chang)的(de)作(zuo)用(yong)(yong)下實現離(li)子的(de)定向遷移，從(cong)而(er)完成水(shui)的(de)深(shen)度(du)除鹽，系(xi)統能(neng)夠(gou)完成樹脂連續不(bu)斷的(de)自動再生(sheng)，無需停機(ji)使用(yong)(yong)酸堿再生(sheng)樹脂，從(cong)而(er)能(neng)連續制取高(gao)品質(zhi)純(chun)水(shui)。

    離(li)子(zi)(zi)交換是用于(yu)制取超純水(shui)的一種傳統技(ji)術。離(li)子(zi)(zi)交換的原理是在一定條件下(xia)，依靠離(li)子(zi)(zi)交換劑(ji)（樹脂）本(ben)身所具有(you)的某種離(li)子(zi)(zi)和待處(chu)理水(shui)中同電(dian)性的離(li)子(zi)(zi)相(xiang)互交換而(er)達到軟化、除堿、除鹽等功能。用于(yu)深度脫(tuo)鹽處(chu)理，產水(shui)電(dian)阻(zu)率動態(tai)可(ke)達到18MΩ.cm。

純水(shui)處理工藝之離(li)子交換(huan)法： 

    雙(shuang)級(ji)(ji)反(fan)(fan)(fan)滲(shen)(shen)透(tou)是將兩套(tao)反(fan)(fan)(fan)滲(shen)(shen)透(tou)裝(zhuang)置(zhi)串(chuan)聯，一級(ji)(ji)反(fan)(fan)(fan)滲(shen)(shen)透(tou)的產(chan)水(shui)(shui)作為二級(ji)(ji)反(fan)(fan)(fan)滲(shen)(shen)透(tou)的入水(shui)(shui)。由于一級(ji)(ji)反(fan)(fan)(fan)滲(shen)(shen)透(tou)的產(chan)水(shui)(shui)水(shui)(shui)質遠遠好于自來(lai)水(shui)(shui)，所(suo)以二級(ji)(ji)反(fan)(fan)(fan)滲(shen)(shen)透(tou)產(chan)水(shui)(shui)的水(shui)(shui)質較單級(ji)(ji)RO系(xi)統產(chan)水(shui)(shui)水(shui)(shui)質更佳，離子、有(you)機(ji)物(wu)和熱源含(han)量更低。
